class JsonField extends CompositeField

PSR1 recommends that each class must be in a namespace of at least one level to avoid collisions.

The return type could not be reliably inferred; please add a @return annotation.

It is generally recommended to explicitly declare the visibility for methods.

                unset($haystack[$key]);

        }

        return $haystack;
